He could also start his own self - training regimen. Izuku is known for his determination. He might study old hero manuals, practice his physical conditioning on his own, and develop his quirk through trial and error. He could then look for opportunities to prove himself in real - world situations, like helping out in local disasters or small - scale crime - fighting.
Another possibility is that he joins a different hero school. Maybe there's a smaller, more specialized school that focuses on a particular aspect of heroism that UA doesn't. For example, a school that specializes in rescue operations could be a great fit for Izuku's empathetic nature.
It could be his mother. She might think that UA is the best place for Izuku to become a hero and force him to go there for his own good, even if he has some doubts or hesitations.
In this kind of fanfiction, Izuku might face a lot of challenges. Maybe he is forced to go to UA by some external power or person against his will. He could struggle to adapt to the new environment at UA, having to deal with difficult classmates or strict teachers. Also, his own self - doubt might intensify as he didn't choose to be there on his own terms.
He might form closer bonds with local heroes in his neighborhood. Since he's not at UA, he would have more time to interact with the heroes who operate near his home. They could become his mentors or friends, guiding him in his hero journey.
One reason could be fear. The life of a hero is full of danger. Izuku might have seen the toll it takes on heroes, like All Might's weakened state. He could be afraid of getting seriously injured or even dying. Another reason might be self - doubt. Despite his initial dreams, he may have come to believe that he doesn't have what it takes to be a great hero, in terms of both physical and mental strength.
One possible storyline could be that Izuku discovers a different quirk within himself. Maybe a latent quirk that was overshadowed by his admiration for All Might and One for All. For example, he could have a quirk related to intelligence amplification, which would make him a brilliant strategist in hero battles.
The story could focus on Izuku becoming a hero - support figure. Instead of being on the front lines, he could use his intelligence to develop new technologies or strategies for heroes. This would be a different path from the traditional hero - becoming storyline.
Izuku's training would become more focused and intense. All Might would know exactly what Izuku needs to improve. He could teach Izuku new techniques and how to better control his quirk. Also, Izuku would have more access to resources related to hero training because of All Might's connections.
All Might could be an interesting choice. He has been a major influence on Izuku, and if he were his father, it would add a whole new layer to their relationship. It could explain why All Might took such a special interest in Izuku from the start.
There could be his friends like Ochaco Uraraka. She might be in a position where she's trying to understand Izuku's situation and help him. Maybe she tries to convince the people forcing Izuku to give him some space.
It could make Izuku seem less honorable. His character has been built on hard work and determination, and copying would be a step back in terms of moral growth.
